The Grinyer System
Discover how the Grinyer System uses digital measuring and factory preparation to deliver precision-fit door replacement without demolition.
The Grinyer System replaces manual tape measuring and on-site cutting with precision digital measuring and robotic factory finishing.
This new process allows us to custom fit fully-finished doors while keeping your existing frames, eliminating demolition and preventing misalignment.
The result is doors installed right the first time, engineered to last, and overall project cost savings passed to you.
​
It is the smarter way to replace interior doors. Period.
